Homework Statement
The Attempt at a Solution
So I was thinking of trying to do row reduction in the hopes that would lead me to an answer.
[itex]\left| \begin{array}{ccc}
0& 1& 1& 2 \\
1&1&1&a \\
1&1&0&2 \end{array} \right| [/itex] → [itex]\left| \begin{array}{ccc}
1&1&1&a \\
0&1&1&2 \\
1&1&0&2
\end{array} \right| [/itex]→[itex]\left| \begin{array}{ccc}
1&0&0&a-2 \\
0&1&1&2 \\
1&1&0&2
\end{array} \right| [/itex]→[itex]\left| \begin{array}{ccc}
1&0&0&a-2 \\
0&1&1&2 \\
0&1&0&-a+4
\end{array} \right| [/itex]→[itex]\left| \begin{array}{ccc}
1&0&0&a-2 \\
0&0&1&a-2 \\
0&1&0&-a+4
\end{array} \right| [/itex]→[itex]\left| \begin{array}{ccc}
1&0&0&a-2 \\
0&1&0&-a+4 \\
0&0&1&a-2
\end{array} \right| [/itex]
So this seems to be telling me that I can choose any [itex]a[/itex] and [itex]x=z=a-2[/itex] and [itex]y=-a+4[/itex]. Am I doing this right?
